SOURCE: jacks show in black and white

You need component output on your Wi. You should have 2 AV jacks on your TV. I am guessing you have a red,white ,and yellow for your WI? That is made to hook up in the AV and NOT the component.If you have red,green,and blue? You might just have a bad cable,that is why it is in B&W. Or hook your Wi to your suround sound AV input if it has one. It is hard to give you all the answers with the info you provided.
But this is a educated guess. hope it helps. Todd

P.S. Be carefull with your controlers, SEVERAL accidents of them hitting the TV and breaking the screen. Play nice. :)

SOURCE: lg model number is 50 PX1D-UC TV does not power

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.

I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors) http://www.shopjimmy.com/.
After replacing these capacitor(capacitors) most likely the normal operation will be restored.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Take care.

Sounds like you took a hit. Unplug your set for 30 minutes and plug it bcck in. It could have just locked up the micro. If this does not fix, unplug the set and take the back off. Plug the set back in and check the powersupply for your 5 volts dc. If it is there, replace your main pcb.

How can i find out more information about older zenith t.v. ?


IF you have the serial number you should find the model number.
The model number is essential for getting more information. One trick is to put 'old Zenith TV images' in Google. You will get lots of pictures. Find the pictures of yours and some will have the model number stated. From there you can do search on that model number. You should be able to locate manuals, etc.

Tv wont turn on


Hello
If there is no power light on the front panel of your TV, ahen you switch it On, the power supply to your tV should be troubleshooted. You haven't given its exact model number here. If so I might send some more details that may help you. Usually, power supply regulator boards fo these type of TVs will have no repair to it, and should be replaced as card basis. OK

Hi. I have a Zenith 42" plasma TV - Z42PQ20 that's


I had this exact problem on my TV, everything said it was the power board. It wasnt, luckily i was able to return that board. It was the YSUS board.

I should have done this this first but this is how i verified the old power board was good. Unplug TV, take the cover off and disconnect the wire harness going to the YSUS, plug TV in and turn on. If led stay blue its the YSUS.
